Toyota Bearing Grading Sheets.......

[Karma Supra]

Just out of interest guys, can anyone confirm if toyota grading seets for specifiying engine bearings are the same for all engines, or are they engine specific???

I cannot get hold of a 1G-GTE specific grading sheet for love nor money (toyota can't help, although they will happilly order the correct bearings if I can get the correct grades...

Does anyone on here have any experiance of them????? I don't really want to go with universal "one size fits all" unless it is my only option....

well if you give me the measurment or an engine that has the same bearings i can give you and acl part number for them! acl are better than the toyota ones so you get better bearings!

Why are ACL bearings better? The only reason I wanted to stay with toyota is because the bearings are graded to the crank/rods/block to keep the tollerances as accurate as possible...

The mains are for 54.991 mm crank diameter ones, 22.03mm wide no.1 and the 19.02mm wide for the rest, The Big ends are 43.993mm crank diameter, and approx 17.03 mm wide. AS the rods and block are still at the machine shop, who seem totally unable to source bearings, I can't measure their i.d.

If I had a toyota grading sheet I could order the exact sized bearings easily and not worry about them being slightly out "one size fits all" bearings....

If that makes any logical sense lol

just by 10thou over, take them to the machining shop and get them to match the crank to the bearings
thats the way my shop wants to do it

at this rate karma ill be finished before you, and i didnt even think id finish lol

[kingmick]

i got the grades somewere ill have a look tomorro!
looks like the 5s-fe 89/94 has the identical main bearings as 1ggte going of the ACL book!

[love ke70]

your probably right, 2s/3s bearings match 1g bearings

Cheers guys...

I know B/E bearings do universal ones;

Mains MS1420 STD @ $ 54.97

Thrusts TW1402 STD @ $12.11

(prices in NZ$) they do the big ends too but I don't have the parts number... I can't get those in time to build my engine anyway, so I thought if I can try toyota and see if they can deliver a bit faster... either way I'll be cutting it all VERY fine!!!!

Kinda daft that toyota can supply the parts, but don;t have the litrature to tell me exactly what parts I need them to supply me!!!

Toyota Australia doesn't keep stock of any Jap import engine manuals, so can't supply this info.
I have successfully ordered bearings for a 1G-GTTE for a customer, i'll have a look at my info when I get back to work.

lol was going to write it all out till i remmebered the digi camera! i kept them big size so you can zoom! this is for the 4ag,but id imagine its the same! hope it helps!







i was hoping to get it to you before you went to sleep! had to go threw 12 boxes of trade books,so it took awhile!

Thankyou very much!!!

Hugely appretiated mate!!!!

Fingers crossed that the grading is the same

[love ke70]

man that n/z company is absolute shit!
didnt have pistons, didnt have 10 thou bearings, blah blah, i spent an extra 200 and bought 4k and 2s bearings etc.
sorry, just had to get that out there...

Thrusts TW1402 STD
that number matches a number from a bunch of people called NDC bearings, im thinking i should be able to get my hands on those...

[kingmick]

how come you got from NZ? its all easy to get here!

acl part No for the thrusts is 8062T for a 4k

[love ke70]

tsk tsk micky boy, keep up
im rebuilding a 1ggte just like him, and ac dont list crap for a 1ggte
and nothing they make matches
and i was gonna go thru that nz company coz they were cheaper, but they are shizzor so no deal
so hmmm...

[kingmick]

you have the specs for the stuff? im sure the 5s ones will prob do the trick if you have the specs ill look it up!

lol and i saw the 4k in your post
